Scientists have achieved a groundbreaking feat: successfully cryopreserving and reactivating sea star larvae. This breakthrough offers a critical step towards restoring populations decimated by disease, particularly in the face of ongoing environmental challenges.
The research, conducted at the San Diego Zoo Wildlife Alliance and the Sunflower Star Laboratory in Monterey Bay, involved cryopreserving larvae of the giant pink star (Pisaster brevispinus). These larvae, stored at -200°C, were later thawed and successfully developed into juvenile forms, marking a first in marine conservation.
This achievement is particularly significant for species like the sunflower star (Pycnopodia helianthoides), which has suffered severe population declines. The ability to cryopreserve larvae opens the door to reintroducing genetically diverse populations and aiding in the recovery of affected ecosystems.
The successful cryopreservation and reactivation of sea star larvae represent a beacon of hope for marine conservation efforts. This technique provides a powerful tool for combating the impacts of disease and environmental threats, paving the way for the restoration of vulnerable marine species.
